There's a fundamental way to remove all energetic ambiguity. Delightfully
simple in theory, miserable in practice:

Perform calorimetry:
Immerse sed fixtures completely in a water bath (!!) in a big-assed
styrofoam picnic cooler, calculate E = m x c x delta Temp.
An unambiguous "Voila". The higher T loses!
(other variables normalized out, factored for lumens, etc.)

The other issue here, w/ electric meters:
Are *they* being fooled by power factors, wave forms, pulses, etc. etc.???
Could the loser in the above calorimetry test (the gold standard), *win*,
according to an electric meter?

Ain't nuthin simple anymore, it seems.

The current draw of the HD special is *more than DOUBLE* that of my local
guy's OLDER T12 fixture!!!! More than double!!! About 1.1 vs. about .5.
Goodgawd....

Yeah, but what's the *real* power being drawn? You can't measure that
without a proper wattmeter (your clampon does NOT do the trick).

You can measure it with this:
